I have modeled a floor slab with a downstand beam that intersects with a continuous column. How can I prevent the slab from resting on the downstand beam but only on the downstand beam?


To ensure that the floor rests only on the downstand beam in this situation (Figure 1), it is recommended to model a minimum opening within the floor surface, see Figure 2.

Figure 02 - Surface with opening

In order to keep the members or the lines of the members integrated in the surface, the function "Connect Lines / Members" has to be applied to the entire model once. Thus, it is ensured that the floor slab continues to rest on the downstand beams.
